Phone on with no battery? - Sprint LG Optimus G

Hey guys basically I upgraded to a nexus 5. I want to turn my Optimus into a permanent installation in my car. But I don't want to leave the battery plugged in all the time. I tried removing it but the phone won't power up without the battery in it. Any simple tricks that I could use?

why dont you want the battery? unless you want it to turn off with the car, then your're gonna need something to do it for you. maybe when power plugs in.

It would be pretty easy to wire the cigarette lighters power wire to the ignition so it only comes on and starts to charge while the car is on.

But I don't want it to charge. The phone is going to be built into the car non removable. I don't want the battery the be constantly trickle charging so it damages it.

You might be SOL here, man. If the phone doesn't turn on with a power source with the battery removed (Like Samsung phones can do), its probably not possible.

What is wrong with just replacing the battery when it dies? Also in another six months the LG OG will probably be under $100 then.

(Q) External battery charging issue

Does anyone else have this issue?
I recently bought the extra battery and charger (that comes with the second batttery) and here within the last few days, I have been charging the unused battery overnight and then it turns greens sometime during the night and then in the morning when I go to put it into my phone, it boots up but states battery life at always less that 60 instead of the full 100%.
So if anyone knows as to why this may be happening, I would greatly appreciate any feedback on this issue that has me pissed.
Thanks in advance and also if somthing like this has been posted then I apologize. I searched and did not see anything along this matter.

So ur not charging battery from ur phone? Try doing that and see if it does the same thing. Is u phone rooted? If it is, than there is a possible resolition.

The external charger may be shutting off too soon. Do what Lord said.
Also please put a subject in when you start a thread like "External charged battery only shows 60%"

Its the same charger I plug into the the spare battery case thing to charge and the light stays red for a long time then it turns green as if its done charging but when inserted battery into phone and power up, its usually around 60% charged or less. But I pull charger out of the spare battery holder and plug directly into my phone and it charges to full ballery.

The battery holder like the phone has a sensor that tells it when to stop. It is working incorrectly....broken.

Never charging to 100%

Whenever i unplug the phone,the battery drops to 99%. Is it Normal or just me?

Happens to me too. Or if it does hit 100 it drops immediately to 99 the moment i take it off the charger.
Well It happened on my dad's E4GT too. But fascinate/OG Epic/Illusion/Evo 3d Which I own never did so!
Take a glass and fill it up with water until it overflows, think of this as your battery. Tip it just a little and you lose some, at which point you will not have 100% of the water anymore. The moment you take it off the charger, it would only make sense for it to immediately go to 99%

Looks like its a common problem! Thanx for ur inputs everyone.

Using battery for the first time

Is it better to gully recharge it before I turn on my phone for the first time or should I drain it down to about 1 % and then recharge it? Or does it not matter? Thanks!

How come? Does it calibrate itself?
The manual says to charge it fully before first time use or long time of no use?

Yes it calibrates itself. these new lithium-ion battery are "smart" battery and they have this little trigger that tells them when the battery is fully charge so they dont get over charged or anything. All you need to do is put the battery and start using the phone.

Im sure li-ion batteries are not to be fully drained. To have long battery life, i think you are to charge as often as possible and never let it fully drain - although the phone seems to check voltage and forcefully shuts down when the battery is really low.
Yeah it really doesn't matter.. And it's really never good to let your battery drop to 1%..I try to never let my lithium ion battery go below 10 if I'm near a charger

Yes a fully drained battery isnt as good as charging like around 5% or so but theres no calibration needed, just put the battery and do your thing.

Charging takes forever! Normal?

Ok so I never really paid attention to how long it takes my phone to charge 100%..
So last night I put my phone on the charger at midnight, woke up at 350am and it was at 55%....
It tok my phone about 5 1/2 hours to fully charge. Normal??
Sent from my SGH-T889 using xda premium
Not normal... My son used to keep putting the charger tip in his mouth and it messed up the pins inside my charging cable.... Tried to clean it with a tooth brush and it worked for a few weeks but started undercharging again. Maybe the pins inside yours are dirty? Bought a new charging cable and it works fine now for me...

Yes I am.
Not sure if it makes any difference but, I have it plugged into an extension cord.
Would plugging it into the wall directly be it?

I have the same issue on jedi x 11 rom saber kernel I believe. When I'm on stock It takes 2 to 3 hours to charge fully. I use the oem charger that came with it as well. I would hate to stop using this rom for that reason.

Mine does the same thing. But I use a desktop dock. If I use just the oem charger and cord it charges fast though.
Adding on a usb extension or using a different usb cord slows it down though.

The computer didn't make a difference, but I took charger out of surge protector and plug directly into wall and it's charging like my stock that charges fine with the surge protector. Can't figure out why stock charges fine with surge protector and jedi x11 rom doesn't. Either way I found my solution.

Its because the dock charger is maybe 800ma output. The wall charger is 2amp charger. The wall charger is best for quick charge. It takes about 1-2 hours with perseus kernel.

Try fixing permissions if the problem started after flashing a rom.

Omg I have the same problem.
I tried charging my Note 2 last night before going to bed. Phone @ 60%. Woke up 7-8 hours later and it was @ 97%. I used an extension USB 3.0 cable (10-15ft) after the AC adapter then hooked up a BlackBerry USB to MicroUSB.
I thought something was wrong w/ my Rom since I plugged it into the wall to charge, and if I do anything w/ screen on, it would end up draining even though plugged in.
I plugged the phone to my comp, which uses the stock Note 2 USB cable, and it charges fairly fast.
My problem is I used to have a Galaxy S3 and Nexus S before that, and it never had this slow charging issue with the same AC adapter + extension + usb-microusb setup.
Im having the same problem .... I would put my phone to charge around 9pm with 20-30 percent and I would wake up at 6am and my phone would be at 80-90 percent charging ...

I installed some monitoring widgets that monitor input charge. I think something is seriously wrong with roms. The input rate is 1600-1800. However it is still taking forever to charge via stock oem wall adapter + cable. I have to reboot to have it charge normally. Not sure what's causing it. Will charge fine, but then after a day or so of use, it ends up charging super slow regardless of where I charge.
Just had my phone charge from 87%-93% in 30-40 minutes.
My Galaxy S3 charged almost twice as fast.

I use Battery Monitor Widget Pro. Also Elixir E2 widgets for tiles that show the charge rates.
Mine charges from like 10% to 100% in like three hours. Running JediM13.
Try cleaning your battery contacts and the contacts for the phone. Might help. Maybe your outlet output is lower? If you can, try cleaning the microUSB port. I usually try to clean my contacts regularly.
I don't know much- just throwing out random ideas
those with slow charge, should try getting a new usb cord. even if your phone is charging doesn't necessarily mean your micro usb cable is 100% working. everytime i start experiencing slow charge i buy a new one and charge time goes back to normal. i've gone through 4 oem samsung micro usb cables since my s2 days.

Hot Swap Batteries?

Is it possible to hot swap batteries in the G3 without turning the phone off?

Nah, power cuts off even with the power plugged in. I don't think it is possible to use the phone at all without the battery inserted.
No, it's not possible. How do you think that would work? You'd have to build some kind of adapter that connects the batteries in parallel, so you can put in the second battery while the first one is still powering the device. But that won't work because you REALLY shouldn't connect a full and an empty battery in parallel.
